SDC 3000 CU

SDC 3000 CU—Central Unit with Integrated Power Supply

The Central Unit controls all functions of Sennheiser’s SDC Digital Conference System for up to 150

conference terminals and up to three SDC3000 CUs can be daisy chained for conferences up to 600.

It is used to program the chairman’s and vice chairman’s units, and to select one of the system’s

three operating modes. These include Request Mode (particpants have to request permission to

speak), the Automatic Mode (the microphone is activated by pressing the MIC key) and the Overrun

Mode (latest participant takes priority over the first participant). Additional audio sources (such as

an interpretation system or an RF Wireless system) can easily be fed into the conference system

via the Central Unit. Fitted with an integrated power supply, the Central Unit can power up to 25

Delegate Units. For larger systems, external power supplies are available separately.
